Child Support Calculation Worksheet

COLORADO CHILD SUPPORT CALCULATION PREPARATION WORKSHEET

NOT JDF 1821 AND NOT A CALCULATOR

This worksheet collects documents and inputs for Colorado's current official
Support Calculator and JDF 1821 Support Worksheet. It does not reproduce
the statutory schedule, parenting-time table, low-income calculations, or
formula. Do not hand-calculate an order from this document.

As of March 2026:

• JDF 1820 Support Worksheet A is discontinued.
• JDF 1822 Child Support Guidelines is discontinued.
• JDF 1821 is the current unified Support Worksheet.

Obtain fresh official tools and forms:

• Colorado Judicial Branch child-support calculator
• Current JDF 1821 Support Worksheet

pre-March-2026 calculator.

Potential-income, unemployment, underemployment, disability, incarceration,
business-control, passive-investor, irregular-income, or income-availability
issue: [DETAILS]

5. Adjusted-Income Inputs

Use the current JDF 1821 and calculator fields. Do not create an “other court-
ordered payments” deduction that the current form does not supply.

Generated monthly adjusted gross income:

• Petitioner: $[AMOUNT]
• Respondent: $[AMOUNT]
• Combined: $[AMOUNT]

7. Adjustment Inputs

For insurance, preserve the total premium, persons covered, children's portion,
and source calculation used by the current form.

8. Low-Income and Self-Support Review

Do not copy fixed low-income amounts from an older worksheet. Let the current
official calculator and JDF 1821 apply the current minimum-order,
low-income-adjustment, self-support-reserve, and no-overnights comparison.

not select the preferred result without a legal and factual basis.
